The window on front passenger door will not open or close, can hear the relay click in the switch assembly and all other functions work. Verified the motor/actuator assembly works by manually jumping the power. Is there a way to trouble shoot the switch assembly? It has two circuit boards inside.

It does sounds like the main switch is out. To be sure here is a guide to help test it with the window switch wiring diagrams below so you can see how the system works and how to replace the switch:
